[mkgmap-dev] exclude words from city / state

Using the locator branch, I noticed that many cities in Austria are not 
findable anymore. The problem is that there are words like "Gemeinde 
Mödling" or "Bezirk Mödling" or "county XYZ". There should be a list 
where one can enter words that get deleted.
That is because for the boundary it is the correct name, but not for 
searching a street.

Also there are problems in Austria in Vienna. Vienna is a state and a 
city, and ideally it should be possible to enter either the district or 
the city into the city field, in order to find a street. Currently it is 
not possible to properly separate cities outside Vienna from districts 
inside Vienna, as they have the same admin_level. But for the ise tags, 
there is a correct specification telling you that districts are not 
cities (from the standpoint of the admin_level, it is correct however to 
classify them the same as small cities outside of Vienna). So in effect 
if one does not enter specific rules for Vienna, address search can 
never work as expected. Admin_level was never intended to be used for 
address searching, hence taking it is flawed and will not provide 
correct results. Ise is intended for address searching, but mkgmap does 
not use it.

In general after using the locator branch, I more and more think, that 
the whole matching is completly the wrong way of doing. Much better to 
support real addresses as entered in OSM, and not do so much guessing. 
Especially support housenumbers, as at least in Germany and Austria 
housenumbers including full ise tags are becoming the norm, and not the 
exception.
Only footways, pathes, or tracks should be matched, as they usually have 
no real address - but then it's rare that one searches for a specific 
path/track/footway, only real use would therefore be
